My cat, Macy is currently about 64 days into her pregnancy, other than her belly looking like she's about to pop, she's not showing any signs of giving birth. She's a small cat anyway, but she's probably not gained 2lbs, could this mean she will have a small litter? She doesn't seem to be "nesting." She's acting like her normal self, could it be because she is so young? I don't want to leave the house for long because I'm not sure how close she is to having them, due to the lack of signs..I want to be here when she has them.
